Pls help choose new Dasher Barrel

[Chrisjan]

Hi,

Please assist me in choosing a new barrel for my 6mm Dasher.
Both barrels are 31" and will be finished at 28". Weight is no issue. This is my f-open rifle that will shoot 107 Sierra Matchkings.

1: Krieger 8tw 4groove Heavy Varmint.
Or
2:Bartlein 8tw 5R 1.25 straight.

I know you first needs to shoot a barrel to measure accuracy, but this decision is purely based on specifications.

I appreciate the input.

Try both but finish them as long as possible. Longer will give you a set back. Larry

You want a straight contour for F Open.

Take your pic, but finish them at 30".......

The 1.250" Straight contour will have some advantage to barrel heat over the HV contour.
And like the others above, I to suggest to finish it as long as possible.

Straight, no taper. Not only takes the heat better, the weight makes it more pleasant to shoot

You could also think 7.5" twist.

Thank you.

I will finish it at 30"

Finishing it at 28" was only because of reading many posts about record groups at that length.
Having it at 30" will make it a pleasure to shoot. I will be adding stock weights to fix the balance.

I just recently did a 6 Dasher on my 40X but I duplicated the contour of the original 40x profile. I did mine in a 7.75 twist.

The contour will only really effect weight. If it's a F Open gun go with the 1.250" str. as it will add weight to the gun.

No difference in how they shoot/heat wise. I just don't see it.
